Box-Cox Transformations and the Taguchi Method: An Alternative Analysis of a Taguchi Case Study
Copyright policy )Box-Cox Transformations and the Taguchi Method: An Alternative Analysis of a Taguchi Case Study
Summary: In a paper discussing the role of transformations in Taguchi analysis Logothesis presented a detailed analysis of experimental data from a plasma etching process. This paper reanalyses the data and reaches substantially different conclusions. In particular the original treatment of components of error variance is questioned, and it is suggested that a two-factor interaction may have been overlooked.
